Application filed September 2G, 1923. Serial No. 664,923.

To all whom t may concern.'

Be it known that I, OTTO F. SCHULDT, a citizen of Germany, residing at Glendale, in the county of Los Angeles and State of California, have invented a new and useful Brush, of which the following is a specification.

This invention relates to devices used for sweeping, cleaning, rubbing, and smoothening.

Une of the objects of this invention is to provide a collapsible or foldable brush.

Another object is to provide the bristles of a brush with swingable'supporting means by which the bristles can be folded when not used.

Another object is to provide the bristles of a brush with supporting means by which thebristles can be folded against the back of the brush.

' Another object is to provide locking means by which the foldable'bristles can be set in operative position.

Another object is to provide operating means by which the whole mass of bristles can be raised and folded in a uniform mannei'. Y v

Another object is to .provide operating means by which the brush mechanism can be conveniently controlled from the outside of the brush. l

Another object is to provide a cover or closing plate for protecting the bristles when in folded or inoperative position, such cover being designed so as to be useful as a mirror when removed from the bristles of the brush.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which-M Fig. 1 is a longitudinal sectional view through the back of a brush, largely on line 11 of Fig. 3, partly broken out to illustrate operating mechanism, a whole set of bristles being indicated in the front terminations, one bristle-holder being illustrated in an upright or raised position, kand another bristle-holder being illustrated in a folded position.

Fig. 18 is a top plan view of a brush with a handle, the removable cover plate serving as a mirror by being provided with a wellpolished plating or actual mirror surface.

The back 18, indicated in Fig. 1, is made in form of a housing for the mechanisms and the folding bristles.

In Fig. 1, a certain form is illustrated in an assembled form in which the several details of Figs. 2 to 12 are parts.'I l

Fig. 13 illustrates a slightly modified.

dui

edge of the outer housing 18, as indicated.

at 2O in Figs. 1, 3 and 7. This rolled-in edge 2O serves to engage with the rolled-in.

edges 21 of the cover-plate 22, as illustrated iii Fig. 7.

Wlieii the bristles are iii folded position, the cover-plate can be pushed over the top of the housing by means of the engagingl edges 2O and 21 thereby covering the bristles in the housing. W

The rolled-in edges of the inner casing 19 can be designed to firmly clinch over the upper edges of the out-er housing 18, for holding the outer housing 18 and the inner casing 19 firmly interengaged, but other means can be provided for interlocking the outer housing 1S and inner casing 19, as rivets orsmall screws, as indicated atv 23 in Fig. 1.

The bristles are preferably mounted on suitable supporting members to allow a raising and folding of the bristles in the back of the brush.

In Figs. 1, 2 and 3, a certain form of supporting member for the bristles is illustrated. Being of sheet material, this `member is folded upon itself in such a manner that the one longitudinal edge 24 engages over the inserted bristles` 25 from one side While the other longitudinal edge 26 engages over the bristles from the opposite side, as illustrated in Fig. 2. The bristles are firmly held between the oppositely clinched edges 24e and 26. The inserted bristles are preferably also clinched at points indicated at 27, to hold the inserted bristles edgewise. The rolled-in back of the bristlesupporting member forms in this manner a tubular-like portion, as indicated at 28, so that a pin may be inserted for a pivot. The supporting member is further provided with flaps or lugs 29, projecting from the ends at practically right angles to the longitudinal sides, having perforations 50 for engaging operating pins. The pins,to be inserted into the rolled-in back at 29, may he on a stationary member; While the pins, to be inserted througl'i tlievlierforations 30 in the lugs 29, must naturally be on a movable member. Y

Stationary pins are indicated at 31 in Fig. 1, the number of pins 31 depending on the number of bristle-holding members desired in a brush. y

Since the bristle-holding members must be inserted into the inner casing 19,. the pins S1 must be inserted from the outside through the inner casing 19 before the inner casing 19 is placed Within the outer housing 18.

rlhe material of the outer housing 1S as Well as the material of the inner casing 19 is preferably as thin as possible to keep the VWeight of the Whole brush Within suitable limits.

Pins are not very durable when just iiisei'ted through a thin casing, and, to also facilitate an assembling, all or a suitable iiiiiiiber of stationary puis are provided oii piii bars. Such pin-bars are placed over the outside of the inner casing 19 with the pins projecting from the bars through the perforations in the inner` casing 19 and into the' rolled-in backs 28 of the several bristle holding members in the back of the brush, as indicated at 32 in Figs. 1 and 8.

A suitable number of bristleeholding members are easily held in suitable jigs or forms, so that pin-bars can readily be applied to bring the pins into the rolle'd-in backs of the bristle-holding members in the brush-back.

The several bristle-holding members are then svvingable Within the inner casing 19. Since the perforations in the lugs 29 of the bristle-holding members swing around the stationary pins thus inserted into the inner casing 19, elongated and curved pei'- forations 39 are provided in the inner cas ing 19 as illustrated in Fig. 1. Other pinbars are placed from the outside of the inner casing 19 through these curved perforations 33, to bring the pins of these bars into engagement with the lugs 29 of the bristleholding members. The movable pin-bar is indicated at 34 in Figs. 1, 3, 4l, 5 and G. The several bristle-holding members, inserted into a brush, can in this manner be raisedand folded in a uniform manner by a shifting or moving of the movable bar or bars 34 in the back of a brush.

In folded position of the bristles, there is no locking of the movable bar necessary, but when the bristles are in raised or operative position the bars are preferably locked so that the bristles may be firmly held in such raised or operative position. One form of locking mechanism is illustrated iii. Figs. 8, 9, 10, 11 and 12.

The movable bai.' 94: is provided with en gaging means, a hook-like vend 3C being` illustrated iii Fig. 5, but it will easily be understood that no specilic engaging means is material long as the movable bar can be controlled in its movements.

A. corresponding Vmember of a form to coact with Whatever form of engaging means has been provided on the movable bar is provided in the locking and outside operating mechanism. In Figs. 8 and 12, a cross head of rectangular shape is indicated at 37, being of a form to easily engage with the cut-out in the hook-end 3G of the movable bar 34 in Fig. 5; The cross head 37 illustrated in top plan view in Fig. 8 as seen inl the direction of the arrow 8 in Fig. 12. In Fig. 12, the cross head 37 yis illustrated in rear side elevation as seen'in the direction of the arrow 12 in Fig. 8. This cross head 37 is made so that it will easily slip back and forth through the cut-ont in the bar-end 36, though always remaining to some extent within the cut-out in order to y maintain control of the bar 34. As stated above, it is not absolutely necessary to locli the bar 34 in the position that corresponds with the folded position of thebristles, but a positive locking of the bar 34 in a position to correspond with the raised and operative position of the bristles is very much desired.

For the sake of simplifying and facilitating an assembling of the device, an extra or a separate plate 38 is illustrated in Figs. 8, 9, 10 and 11, though this is not absolutely necessary since the different notches and cut-outs can justas easily be provided directly in the outer housing 18. Notches 39 are provided in the beads or bar-like projections 40 in the rear face of the plate 38. These notches 39 allow the cross-head to become iirmlyseated against sidewise movements so as to hold the interengaged bar 34 against longitudinal shifting. This locking position, illustrated in Fig. 8, corresponds with the raised and operative position of the bristles. A slight pushing inwardly into the housing frees the cross-head from the notch-engagement so that the cross-head can be moved in a sidewise direction to eventually reach the position indicated in dotted lines at 4l in Fig. 8. As long as the cross-head is not in the notches 39, the cross-head is free to slide over 'the beads or bar-like projections 40. The crosshead is provided with guiding members or portions 42 which are of a form to easily slide back and forth between the beads or bar-like projections 40, to prevent a twisting orturning of the cross-head while disengaged from the notches 39, assuring a maintenance of the cross-head in proper relation to the movable bar 34, and assuring a proper alignment of the cross-head with the notches whenever the cross-head is moved in that direction.

The cross-head is provided with an outwardly extending stem terminating in a button-like member 43, by which the mechamsm can be operated from the outside. A helical spring 44 is inserted between the button 43 and the plate 38, to assure a vdrawing of the cross-head into the notches.

Instead of using pins for supporting and operating the bristle-holding elements, a slightly modified form is illustrated in Fig. 13, in which only one operating bar ire-` quired without any small pins. The operating bar 45 is disposed between the sides of the outer housing 18 and the inner casing 19 in a similar manner as the pin-bars 32 and 34 of the form illustrated inl Figs. 1 to 8. rlhe ends of thebristle-holding elements are merely of flat form as indicated at 46, instead of the tubular back 28 and the perforated lugs 29 of the form illustrated in Fig. 2. These flat ends 46 of the bristleholding elements are disposed through the perforations 47 in the opposite sides of the inner casing 19, to extend into the space between the sides of the outer housing 18 and the inner casing 19 to be in reach of the bar 45. The bar 45 is provided with cutouts or notches 48, of which the edges are apt to become disposed parallel to the inclined edges of the perforations 47 in the sides of the inner casing19, so that the iiat ends 46 of the bristle-holding elements can be held by the inclined edges of the bar 45 against the inclined edges of the perforations 47, to bring the bristle-holding elements to folded and raised positions in :i similar manner as described above with reference to the illustrations in Figs. l to 8. A spring 49 is disposed above the bar 45 within the space between the sides of the outer housing 18 and the inner casing 19, vto hold the bar 45 and thereby the bristle-holding elements in the desired positions. 1

Another slightly modified form is illustrated in Figs. 14, 15, 16 and 17. The operating bar 50, illustrated in F ig. 16, is provided with teeth 51, to co-operate with gearlike members 52, illustrated in Figs. 14 and 15. This bar 50 replaces the bar 34 of the first-described form, and may also replace the bar 45 ofthe modified form in Fig. 13.

Thegear-like members 52 are provided on a shaft 53, as illustrated in Fig. 14, in a transverse direction so that the shaft can be turned by a moving of the gear members. The shaft 53 is preferably provided with bearing portions as indicated at 54 in Figs. 14 and 15, to facilitate a turning of the shaft 53, while the larger portion of the shaft V53 may be flattened to reduce its weight and its size. Around this flattened portion of the shaft, the bristles are preferably folded, as indicated at 55 Areference to the illustration of Fig. 17.

l in Fig. 1 7, 'the whole being lnclosed by the covering do not limit myself to details of this liind, and wish it. understood that the sev. eral details can easily be modified in one direction or another within the scope of the appended claims.

'Ihe cover-plate 22 is preferably well polished or even provided with a mirror face, adapted to be used as a mirror when removed from the brush in connection with a hair-brush form as illustrated in Fig. 18, the brush being in such a case preferably provided with a handle member 57. rIhe device may, of course, also be used as a mirror while the cover-plate 22 is in covering position as illustrated.

Having thus described my invention, I claim:

l. In a brush, a back embodying inner and outer sections of elongated cupped form `ested one within the other with the side walls spaced apart', operating bars disposed within the spaces between the side walls of the inner and outer sections, the inner section having a plurality ,of perforations in its side walls, the said bars being provided with pins projecting through the perforaticns in the inner section, the pin-bars being arranged in sets of which one set is comparatively stationaryk while the otherl set is shiftable within the space between the sections of the back, bristle-holders disposed in the depression of the inner section in an operative engagement with the pins, and operating means operatively engaged with one set of pin-bars whereby the bristleholders may be tilted back and fortlr 2. In a brush, a back portion de# pressed in its center to form upright side walls of rectangular forni, two of the upright walls disposed opposite each other having a plurality of perforations near the bottom and having another plurality of elongated perforations above and arched at an even radius around the irst-narned perfor tions.

3. In a brush, a back made of inner and outer sections nested one within the other and normally forming the single back for a brush, the lupper edges of the upright walls of the inner section being bent upon themselves outwardly so as to engage over the upper edges of the upright walls of the outer section'thereby forming closed spaces between the upright walls of inner and outer sections of the back substantially as and for the purpose described.

4. In a brush, a back embodying an inner and outer section each being depressed in the center so as to forni upright flanges spaced between the inner and outer section, the inner section having perforations, two sets of pin-bars disposed in the spaces between the inner and outer section having pins projecting through the perforations in the inner section, bristle-holders operatively mounted within the inner section roelzable on one of the sets of the pin-bars, and operating means for actuating another set of the pin-bars and thereby the bristle-holders.

5. In a brush, a back embodying an inner and outer section nested one within the other with the side walls spaced apart, the inner section having a plurality of round perforations near the bottom of two opposite side walls and having another plurality of elongated perforatiens spaced and arched above the first-named perforations, bristle-holders mounted within the inner section by means of pin-bars disposed in the spaces between the inner and outer section and having pins pro- `iecting through the round perforations near the bottom of the inner section forming pivots for the bristle-holders, other pin-bars disposed in the spaces between the inner and outer section having pins projecting through the elongated arched perforations and operatively engaging with the pivotally supported bristle-holders, and operating means embodying locking means in operative connection with the second-named pin-bars for controlling the movements of the bristleholders to be in operative and in folded position.

6. In a brush, a bristle-holder made of sheet material folded upon itself and having lugs on opposite ends bent at practically right-angles to the longitudinally folded portion, the said lugs having perforations.

In testimony that I claim the foregoing as my invention I have signed my name.
